Arden Hills: TCAAP consultant outlines possible development mix

How much housing, office and retail could Ramsey County's share of the redeveloped Twin Cities Army Ammunition Plant in Arden Hills support?

The Cunningham Group, planning consultants for the city of Arden Hills, are proposing 1,700 units of housing on 168 acres, 2 million square feet of office space on 156 acres and 300,000 square feet of retail space on 18 acres.

The future TCAAP development -- still in a conceptual proposal, with no specific developer attached -- would also include 53 acres of open space and a 26-acre spine road. Thirteen acres would be mixed-use for both housing and commercial uses.

The proposal was unveiled Monday night, and Arden Hills Mayor David Grant said it was preliminary and subject to change.

The plan will be presented to a joint city-county planning authority in early 2014, as well as the city planning commission.

Environmental cleanup of the 400 acre site, the state's largest Superfund site, is underway, and redevelopment would likely move forward in stages over the course of several years.
